Information analysis often involves decomposing data into sub-groups to allow for comparison and identification of relationships. Breakdown Visualization provides a mechanism to support this analysis through user guided drill-down of polyarchical metadata. This metadata describes multiple hierarchical structures for organizing tuple aggregations and table attributes. This structure is seen in f...

We transform a Muller game with n vertices into a safety game with (n!)3 vertices whose solution allows to determine the winning regions of the Muller game and to compute a finite-state winning strategy for one player. This yields a novel antichain-based memory structure and a natural notion of permissive strategies for Muller games. Moreover, we generalize our construction by presenting a new ...

Large collections of data, e.g. archives of POS (point-of-sale) in the consumer packaged goods as well as in prescription drugs, are typically iteratively classiied by a hierarchy 6] on the members of some attributes. Most of the fortune 500 businesses have found ways to consolidate the data archive into a relational database manager. One of the most common steps in \investigative data explorat...

In view of the quark mass hierarchy and in the assumption of the up-down parallelism, we derive two phenomenologically-favored patterns of Hermitian quark mass matrices from the quark flavor mixing matrix. We compare one of them with two existing Ansätze proposed by Rosner and Worah and by Roberts et al, and find that only the latter is consistent with the present experimental data. PACS number...
